Implement gradio client (work in progress)

[abrichr]

There appears to be an issue using gradio_client (any version) with the original gradio version 3.42.0:

client.py:

from gradio_client import Client

client = Client("http://3.84.210.111:6092/")
result = client.predict(
    # str (filepath or URL to image) in 'Input' Image component
    "https://raw.githubusercontent.com/gradio-app/gradio/main/test/test_files/bus.png",
    # int | float (numeric value between 1 and 3) in 'Granularity' Slider component
    1,
    # str in 'Segmentation Mode' Radio component
    "Automatic",
    # int | float (numeric value between 0 and 1) in 'Mask Alpha' Slider component
    0,
    # str in 'Mark Mode' Radio component
    "Number",
    # List[str] in 'Annotation Mode' Checkboxgroup component
    ["Mask"],
    fn_index=2
)
print(result)

Modifying client.py to pass a dict instead:

result = client.predict(
    {
        "image": "https://raw.githubusercontent.com/gradio-app/gradio/main/test/test_files/bus.png",
    },
